Chapter 1: Q20DQ (page 356)

If a metal wire has its length doubled and its diameter tripled, by what factor does its Young's modulus change?

Short Answer

Expert verified

Thus, Young's Modulus of the wire remains unchanged.

Step by step solution

01

Young's Modulus

The Young's Modulus is a physical property of any material mostly elastic in nature that determines the ease of deformation of that material with respect to stress and strain applied to it.

02

Young's Modulus

Given, that a wire is transformed by doubled by its length and tripled by its diameter.

Since Young's modulus is a property independent of the dimensions of the medium or material, therefore, the change in the dimension would not affect the Young's Modulus of the wire.

Hence, this is the required answer.

A Fast Pitch. The fastest measured pitched baseball left the pitcher鈥檚 hand at a speed of 45.0m/s. If the pitcher was in contact with the ball over a distance of1.50mand produced constant acceleration, (a) what acceleration did he give the ball, and (b) how much time did it take him to pitch it?

On a training flight, a student pilot flies from Lincoln, Nebraska, to Clarinda, Iowa, next to St. Joseph, Missouri, and then to Manhattan, Kansas

(Fig. P1.66). The directions are shown relative to north: 0掳is north, 90掳is east, 180掳is south, and 270掳is west. Use the method of components to find (a) the distance she has to fly from Manhattan to get back to Lincoln, and (b) the direction (relative to north) she must fly to get there. Illustrate your solutions with a vector diagram.

The most powerful engine available for the classic 1963 Chevrolet Corvette Sting Ray developed 360 horsepower and had a displacement of 327 cubic inches. Express this displacement in liters (L) by using only the conversions 1 L = 1000 cm3 and 1 in. = 2.54 cm.

A car is stopped at a traffic light. It then travels along a straight road such that its distance from the light is given byxt=bt2-ct3, whereb=2.40m/s2andc=0.120m/s3. (a) Calculate the average velocity of the car for the time interval t = 0 to t = 10.0 s. (b) Calculate the instantaneous velocity of the car at t = 0, t = 5.0 s, and t = 10.0 s. (c) How long after starting from rest is the car again at rest?

A cube is placed so that one corner is at the origin and three edges are along the x-, y-, and z-axes of a coordinate system (Fig. P1.80). Use vectors to compute (a) the angle between the edge along the z-axis (line ab) and the diagonal from the origin to the opposite corner (line ad), and (b) the angle between line ac (the diagonal of a face) and line ad.
